This invention relates to electric telegraphs or transmitting.-apparatus and more particularly to recordin or writing mecha-- nism asmay be connecte therewith. 7 One feature of the invention resides in antransmitted communications are written continuously and automatically inthe formFof or this purpose a plurality of writing devices or membersare arran ed in spatial relation, the distance. between t e writingdevlces cora recording surface or web intended to re- 2 .gram while saidsurface is moved at right angles or practically or nearly at rightangles with re ect to the direction of move mentof the sai writingdevices. Each such writing device is'an independent uni-t, that is tosay individually ca able of producing upon the paper a line 0 charactersor text iven to a writing device of a type whic currently describesletter curves, such as will be described below. The s eed of the writingde-' vices on the one ban and the speed of the paperon theother hand isregulated in such a manner. that when one .of the writing de- Vices hasbeen moved by as much as the length of a line, the web will haveadvanced as much as the distance between two lines.

simultaneously from the same impulses and The'result'is that as soon asone of the writ ing'devices has finished a line, the next writ:

.ing device is set to commence-the writing of the next line.When-feeding continuously both-the web and the writing devices at therequired rate of speed it w1ll' be advantageous to allow said surface orweb to cross somewhat obliquely the path "of the writing device inaction so that the lines written may appear normally square upon thesurface an not sloping.

- he writing devices may be caused to work "to cooperatein such a mannerthat om device may start a new line-while thepreced-l ing devicefinishes the preceding line. The

text at the endx'ofgonej line may-then overlapll with the text at thebeginning of a new line, m other words the end of one line will be re-'peatedat the beginning of the new line so as to insure a cleartransition'from one line to the other. 1

In its preferred embodiment the invention avails itself of a writingdevice where component movements induced from a tnansmitter are composedin the receiving apparatus to produce a continuous letter. curve suchmethod being broadly known from the socalled Pein curves to betransmitted a e decomposed into their components and the transmitteremits I s stem disclosed in my Patent 1 i No. 1,751,781 led Sept. 29,1925). According to this system the characters or letter electricenergies which vary according to the course of the component curves ofthe char-.

acters to be transmitted. The electric ,energy variations are then,in,th e receiver, transformed mto'spatial movements and caused toactuate a writmg memberor implement in such a manner that it describesthe resultant of every two component curves ertaining to a character,and thus, the ciiarponent movement as induced from the trans- Qmitter.With ro rarran ement the writ ing member wi l t us descri e thecharacter curve resulting from said component move-. ments.

Another feature provides rotary armatures to formthe controlmembers forsaid guiding' rods. Other features and advantages will appear.hereinafter. The invention is illustrated dia ammatically andbyway'ofrexample on t e'accompanying drawing on which Figure 1 ,is a planofa Pein writing device arranged upon a conveying member andbeing movedover a paperband upon which the transmitted charaeters..:are Written;Figure 2 is a side- .view of the arrangement and combination ,there maof parts shown in Fig. 1; Figure 3 shows the arrangement of three Peinwriting devices upon a common conveying member in such a manner thatthey are moved successively over the paper band provided for thereception of thecommunication or message or telegram transmitted, thisfigure being drawn to a reduced scale relatively to Figs. 1 and 2;Figure 4 explains the cinematic relations arising when the writingdevice and the paper band are-moved simultaneous- 1y; Figure 5 shows themeans for driving the writing device and the paper band; Figure6 showsthe wiring diagram of the receiving apparatus; and Figure 7 shows arelay arranged in series with the Pein writingdevices.

eferring to Figs. 1 and 2, 1 are two magnet frames magnetized more orless by the energy variations transmitted by the transmitter. Themagnetization of the one magnet frame takes place in conformity with thecourse of the one component curve of the character transmitted, and themagnetization of the other magnet frame takes place in conformity withthe other componentcurve of that character. The magnet frames 1 act uponthe armatures 2 which are turned more or less according to the.intensityof the magnetization of said frames. The armatures are-connected by rods3 and 4 with a writing member orwriting pin 5, the movement of which isthe resultant of the movements given to the two armatures 2. Thisresultant is, however, nothing else than the succession of linesconstituting the transmltted character. The pin 5 Writes the transmittedcharacter upon a sheet of paper 6; it communicates with an inkreceptacle 8 by means of a tube or hose 7.

In order to write down the transmitted characters in successive lines,one beneath the other, as in Fig. 3, the writing device 1-5, 7,8 ismoved along over the sheet of paper 6which, at the same time, is,fedforward at right angles or nearly at right angles with respectto thedirection of motion of said device. In-order to move the writing devicealong over the sheet of pa er,

be used, for instance, an end ess band 9 Fi 3) running over two rollers10a and 10 The several writing devices are aflixed to saidrband. incertain distinct distances from one another, these distances being sochosen that in that moment l in which any one of themhas arrived at'theend of a line, the next thereof'has arrived at the commencement of thefollowing line. In. electrical regard all-writing devices are connectedinparallel. ,In the constructional form illustrated in Fig. 3, allwriting devices are secured to a'common band- 9 so that all are movedsimultaneously and with absolutely the same speed. .There are emmove thewriting devices not actually at.

right angles with respect to the paper, but somewhat obliquely, thedegree of the ob liquity being such that the just active writing deviceis moved not only from the one edge to the other edge of the paper, butalso in the direction of motion of the paper by so much, as correspondsto the distance between two lines. There is attained inthis way that inspite of the continuous forward feed of the paper the lines are writtenrectangularly with respect to the paper, as appears from Fig. 4, inwhich the dotted oblique line indicates the direction of motion of theconsecutive writing devices, and 6 dc notes the distance between theparallel lines which extend quite correctly at right angles with respectto the paper.

The endless band 9 is moved uninterruptedly by rollers 17a and 17b whichare provided with teeth 18 engaging perforations 19. provided in thepaper, as shown, so that the paper is drawn along by the rotatingrollers 17a and 171). In order to provide h for a good contactbetween'these rollers and the paper pressing-on rollers 20 are provided.

As the movement of the paper and the movement of the conveying band mustbe in a certain relation to one another, it is requisite to drive thepaper feeding rollers 17a and 17b and the band driving rollers 10a and106 by a motor 21 common to them all. This K motor drives a-co g-wheel23 by the intermediary of a pinion 22; said'cog-wheel is se cured to ashaft 24, to which is afiixed the paper band roller 1712; this roller isconnected with the other paper band roller 17?) by means of a chain 25so that both these rollers are driven simultaneously and with the samespeed. A bevel-wheel 25 keyed to the shaft 24 meshes with a bevel-wheel27 secured to a shaft '28.. This I latter is connected with a worm 29drivin a worm-wheel 30. This wheel turns 'anot er pair ofbevelwheels 31,32; the latter of these wheels is aflixed to the shaft of the conveyingband roller 10a, so that this roller can be, and is,- rotated by themotion-transmitting means described. The

rollers 10a and 106 are connected with one.

35 with each of the writing devicesas shown in Fig. 6'. Each two oftheserails conducta current, the intensity of which is varied aci the exampleabove described-several cording tothe course or configuration of thecomponent curves of the just transmitted-- charaeter. .The two magnetframes 1 of'the writing. devices are connected up to the cur-'rent-carrying rails 34 in such a manner thatalways' one of them, of eachwriting device, is in conductin connection with one pair of said rails,and filBPBfOIG, the respective three magnet frames are connected inparallel.

There are, thus, produced in each of the three writing devices, and'inall of them at the same time, such variations of current as correspondto every two component curves. The current is supplied to the rails 34by brushes writing devices are actuated ata time, it be comes 1n manycases requisite to lnsertlnto the circuit of every one thereof a'relayandto' actuate the writing number itselfbymeans of a localv current,because the current arriving from the transmitter is not strong enoughto actuate two or more writing devices. A suitable .relay is shown inFig. 7. In this figure only one magnet frame is shown this'frame ismagnetized in correspondence with one of the two component curves, andsaid figure shows, besides, only that part of the relaywhich is intendedfor the control of that one magnet frame; In reality, the parts s own inFig. 7 must'be assumed to be doubled, hen

. it will be possible to cause both com onent I er portion of theresistance 14 is inserted into curves to act upon the writin pin. herelay part shown in Fig-5 conslsts' chiefly of a magnet frame 11designed similar to the magnet frame shown in Fig. 1 said ma etframe(11) is magnetized in correspon ence with the course of a componentcurve .of the transmitted character by the electric energy variatlonsarr1v1ng from the transmitter, whereby" the armature 12 is caused tooscillate onits ax1s, these oscillations corresponding also to thecourse of the component curve. The armature 12 is connected with an arm13 slidmg over a variable resistance 14; this latter and sai arm areinserted into a circuit 15 containing also the battery delivering the10- cal current. According as a larger or small:

the circuit by the arm 13, the intensity .of the current flowing in. thecircuit 15 will be depon'ent curves.
